The peak value of an alternating current in a 1500-W device is 6.4 A. What is the rms voltage across it July 31, 2021 by Huyền Thanh The peak value of an alternating current in a 1500-W device is 6.4 A. What is the rms voltage across it
Answer: 6787.5 V Explanation: From the question, P = IV………………… Equation 1 Where P = Power, I = rms current, V = rms voltage. make V the subject of the equation V = P/I…………….. Equation 2 Given: P = 1500 W, I = 6.4/√2 = 4.525 A Substitute these values into equation 2 V = 1500(4.525) V = 6787.5 V Hence the rms voltage = 6787.5 V Reply
Answer:
6787.5 V
Explanation:
From the question,
P = IV………………… Equation 1
Where P = Power, I = rms current, V = rms voltage.
make V the subject of the equation
V = P/I…………….. Equation 2
Given: P = 1500 W, I = 6.4/√2 = 4.525 A
Substitute these values into equation 2
V = 1500(4.525)
V = 6787.5 V
Hence the rms voltage = 6787.5 V
