Question

A 12 volt car battery pushes a charge through the headlight circuit with a resistance of 8.5 ohms. How much current is passing through the circuit

Answer 1

Data:
i (current) = ? (Amps)
R (resistance) = 8.5 Ω
V (voltage) = 12 volts

Formula:
$V = R*i\to \boxed{i = \frac{V}{R} }$

Solving:
$i = \frac{V}{R}$
$i = \frac{12}{8.5}$
$\boxed{\boxed{i \approx 1.41\:Amps}}\end{array}}\qquad\quad\checkmark$
