The instantaneous values of a sinusoidal waveform is given as the “**Instantaneous value = Maximum value x sin θ** ” and this is generalized by the formula. Where, V_{max} is the maximum voltage induced in the coil and θ = ωt, is the rotational angle of the coil with respect to time.

What is peak value? Peak value is defined as **the maximum value reached by an alternating quantity in one cycle** is known as Peak value.

RMS or root mean square current/voltage of the alternating current/voltage represents the d.c. current/voltage that dissipates the same amount of power as the average power dissipated by the alternating current/voltage. For sinusoidal oscillations, **the RMS value equals peak value divided by the square root of 2**.

Most books define this as the “amount of AC power that produces the same heating effect as an equivalent DC power”, or something similar along these lines, but an RMS value is more than just that. **The RMS value is the square root of the mean (average) value of the squared function of the instantaneous values**.

The effective value of an alternating current is that **current that will produce the same heating effect as an equivalent direct current**. The effective value is called the root mean square (r.m.s.) value and whenever an alternating quantity is given, it is assumed to be the r.m.s. value.

The instantaneous value of current in an AC circuit is **i = 2sin ( 100pit + pi/3 ) A**.

Current is constituted by the flow of charges. **Instantaneous current is given by the amount of charge passing through a conductor at any given instant of time**.

We know that voltage rating is the most rms also known as root mean square value of the voltage. So we can say that the peak voltage in a 220 V, 50 Hz Ac source is **311 V**.

The instantaneous value of alternating current and voltage are given as **i = 1/√2 sin(100 πt) A and e = 1/√2 sin(100 πt + π/3) volt**. The instantaneous value of alternating current and voltage are given as i = 1√2 sin (100 πt) A and e = 1√2 sin(100 πt +π3 ) volt. Find the average power in watts consumed in the circuit.

The average value of sinusoidal alternating voltage or current over one cycle is **zero**. It is because the area of positive half cycle is exactly equal to the area of negative half cycle.

The instantaneous values of a sinusoidal waveform is given as the “**Instantaneous value = Maximum value x sin θ** ” and this is generalized by the formula. Where, V_{max} is the maximum voltage induced in the coil and θ = ωt, is the rotational angle of the coil with respect to time.

Answer: The instantaneous value is “**the value of an alternating quantity (it may ac voltage or ac current or ac power) at a particular instant of time in the cycle**”.

The science process skills **help students to understand phenomena, answer questions, develop theories and discover information** (Martin, 2009). They are essential in developing ideas (Harlen & Qualter, 2004) and they increase academic achievement in science learning (Aktamis & Ergin, 2008) .

As shown in the databook, the max operating temperature for the indoor Bobcat Miner 300 is 60C. **Do NOT place it outside if it risks heat exposure, which will cause CPU crashing**. DIY weatherproofing such as placing the miner in a sandwich bag is not recommended.

- Frictional Unemployment. Frictional unemployment is when workers change jobs and are unemployed while waiting for a new job.
- Structural Unemployment.
- Cyclical Unemployment.
- Seasonal Unemployment.
- Technological Unemployment.
