Question
- according to ohms law, voltage = current x resistance
- if a 1.5 - v battery is connected in a simple circuit to a light - bulb with a resistance of 8 ohms, the amount of current flowing through the circuit is
- in a series circuit, each device that is added to the circuit decreases the
- if you multiply the voltage in a circuit by the current, you are finding the of the circuit.
Step1: Recall Ohm's law formula
Ohm's law is $V = IR$, where $V$ is voltage, $I$ is current and $R$ is resistance. We want to find $I$, so we can rewrite the formula as $I=\frac{V}{R}$.
Step2: Substitute given values
Given $V = 1.5$ V and $R=8$ ohms. Substitute into $I=\frac{V}{R}$, we get $I=\frac{1.5}{8}= 0.1875$ A.
Step3: Recall power formula
The power $P$ in a circuit is given by $P = VI$. So when we multiply voltage by current, we are finding the power of the circuit.
