In a coil with an inductance of 0.3 H, a current flows, which changes according to the law i = 5sin200t. calculate the maximum voltage across the coil.
To calculate the maximum voltage value on the specified coil, use the formula: Um = Im * ω * L.
Variables: Im – maximum current (Im = 5 A at sin200t = 1); ω – angular frequency (ω = 200 Hz (sinωt = sin200t)); L – inductance (L = 0.3 H).
Let’s make a calculation: Um = Im * ω * L = 5 * 200 * 0.3 = 300 V.
Answer: The maximum voltage on the indicated coil is 300 V.
