Voltage is measured in parallel.
A parallel circuit is a type of electrical circuit that contains two or more branches that are connected to the same voltage source. In a parallel circuit, the current can flow through any of the branches, and the total current is equal to the sum of the currents in each branch.
To measure the voltage in a parallel circuit, you can use a voltmeter. A voltmeter is a device that measures the difference in electrical potential between two points. To use a voltmeter, you connect the positive lead of the voltmeter to one point in the circuit and the negative lead to another point in the circuit. The voltmeter will then display the voltage difference between the two points.
The other options are incorrect because:
- In a series circuit, the current flows through all of the components in the circuit. This means that the voltage drop across each component is equal to the total voltage in the circuit. Therefore, you cannot measure the voltage across a single component in a series circuit.
- After breaking the circuit, there is no current flowing through the circuit. Therefore, you cannot measure the voltage in a circuit that has been broken.
- After checking resistance, the voltage in the circuit may have changed. Therefore, you cannot measure the voltage in a circuit after checking resistance.
- After checking current, the voltage in the circuit may have changed. Therefore, you cannot measure the voltage in a circuit after checking current.
