Question

How do the current and coltage readings compare to before the wires were switched. Explain how to interpret them physically?

Answer 1

• The potential difference between two locations in an electric circuit is measured using a voltmeter.
• If the electricity passes through the voltmeter it shows deflection.

What is the purpose of a voltmeter?

• A voltage meter, usually referred to as a voltmeter, is a device that measures the voltage, or potential difference, between two points in an electrical or electronic circuit.
• volts is the unit of voltmeter(volts, millivolts, kilovolts)

What is the explanation for the link between current and voltage?

• Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperatures remain constant.

What is ohm's law in circuit?

• V = IR, where V is voltage, I is current, and R is resistance, is known as Ohm's Law.
• If you know the voltage of the battery in the circuit and how much resistance is in the circuit, you may use Ohm's Law to identify properties of a circuit, such as how much current is flowing through it.
