Question

an electric heater works by passing a current of 94 a though a coiled metal wire, making it red hot. if the resistance of the wire is 1.5 ohms, what voltage must be applied to it?
answer
check
what are the units for your answer?
select one:
ohms
volts
amps
check

Explanation:

Step1: Recall Ohm's Law

Ohm's Law: $V = I \times R$
Given: $I = 94\ \text{A}$, $R = 15\ \Omega$

Step2: Calculate voltage

Substitute values: $V = 94 \times 15 = 1410$

Step3: Identify voltage unit

Voltage unit is volts.

Answer:

1410
volts
