Question

If the voltage is 120 V, and the desired current is 5 A, what resistance must be in the circuit?A.0.04 ΩB.600 ΩC.24 ΩD.5 Ω

Answer 1

Given:

Voltage = 120 V

Current = 5 A

Let's find the resistance in the circuit.

To find the resistance in the circuit, apply Ohm's law:

`\begin{gathered} V=IR \\ \\ \end{gathered}`

Where:

V is the voltage

I is the current

R is the resistance.

Since we are to find resistance, rewrite the equation for R:

`\begin{gathered} R=(V)/(I) \\ \\ R=\frac{120\text{ V}}{5\text{ A}} \\ \\ R=24\text{ }\Omega \end{gathered}`

Therefore, the resistance in the circuit must be 24 ohms.

ANSWER:

C. 24 Ω
