Question

Select the correct answer from each drop-down menu. Rewrite the formula to find voltage. The formula for electrical power (P, in watts) is where V is the voltage in volts and R is the resistance in ohms. For a particular brand of water heater, R is 32 ohms and P is 0.5 watts. The formula to find V is , and the voltage at which the heater operates is volts.

Answer 1

Answer:

V = 4 volt

Step-by-step explanation:

Given: Electrical power (w) P = 0.5 watt and resistance R ( Ω ) R = 32 ohm

Voltage V = ? (volt)

Formula for calculating electrical power is:

P = V² / R => V² = P · R  => V ) √P · R = √0.5 · 32 = √16 = 4 volt

V = 4 volt
