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.

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

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

current in the circuit at time t is /, then the power delivered to the resistor is
