Question

  1. when a wire is made thicker, its resistance
  2. the unit used to measure electric current is the ampere
  3. according to ohs law, voltage = current × resistance
  4. 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
  5. in a series circuit, each device that is added to the circuit decreases the
  6. if you multiply the voltage in a circuit by the current, you are finding the
  7. electric energy used on your electric bill is measured in

Explanation:

Step1: Recall Ohm's law formula

Ohm's law is $V = IR$, where $V$ is voltage, $I$ is current and $R$ is resistance. We need to find $I$ when $V = 15$ V and $R=8$ ohms.

Step2: Rearrange the formula to solve for current

From $V = IR$, we can get $I=\frac{V}{R}$.

Step3: Substitute values

Substitute $V = 15$ and $R = 8$ into the formula: $I=\frac{15}{8}=1.875$ A.

Answer:

$1.875$ A
