Question

an electric heater works by passing a current of 93 a though a coiled metal wire, making it red hot. if the resistance of the wire is 1.4 ohms, what voltage must be applied to it?
answer:
check
2
what are the units for your answer?
select one:
volts
ohms
amps

Explanation:

Step1: Recall Ohm's Law

Ohm's Law: $V = I \times R$

Step2: Substitute values

$V = 93\ \text{A} \times 1.4\ \Omega = 130.2$

Step3: Identify unit

Unit of voltage is volts.

Answer:

130.2
volts
