A radio operating at 3.0 volts and a constant
temperature draws a current of 1.8 × 10^−4 ampere.
What is the resistance of the radio circuit?
(1) 1.7 × 10^4 Ω (3) 5.4 × 10^−4 Ω
(2) 3.0 × 10^1 Ω (4) 6.0 × 10^−5 Ω

Answer:

(1) 1.7×10⁴ Ω

Explanation:

According to Ohm's law, the voltage drop is equal to the current times the resistance.

V = IR

3.0 V = (1.8×10⁻⁴ A) R

R = 1.7×10⁴ Ω
