Question

a circuit contains a 2.9 volt battery and a bulb with a resistance of 2 ohms. calculate the current.
answer:
check
what are the units for your answer?
select one:
ohms
volts
amps
check

Explanation:

Step1: Recall Ohm's Law

Ohm's Law: $I = \frac{V}{R}$
Given $V=2.9\,\text{V}$, $R=2\,\Omega$

Step2: Calculate current

$I = \frac{2.9}{2} = 1.45$

Step3: Identify unit of current

Unit of current is amps.

Answer:

1.45
amps
