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

We can do this using V=IR

Substituting values in we get 3 = (1.8x10^-4) x R
R=3/0.00018
R=16666 = 17000 to 2sf

Therefore, the resistance of the radio circuit is 1.7x10^4 Ohms
