Physics - Voltage

What is voltage?

Voltage, also known as potential difference, is the measure of electric potential energy per unit charge.

What unit is voltage measured in?

Voltage is measured in volts (V).

What is the formula for calculating voltage?

Voltage (V) = Energy (E) / Charge (Q).

What does a higher voltage mean?

A higher voltage means more energy is available to push charges through a circuit.

What is the symbol for voltage in electrical equations?

The symbol for voltage is "V".

What is a battery?

A battery is a device that stores chemical energy and converts it to electrical energy, providing voltage.

What is the difference between AC and DC voltage?

AC (alternating current) voltage changes direction periodically, while DC (direct current) voltage flows in one direction.

What is the potential difference across a component in a circuit called?

The potential difference across a component is called the voltage drop.

What happens to voltage in a series circuit?

In a series circuit, the total voltage is divided among the components.

What happens to voltage in a parallel circuit?

In a parallel circuit, the voltage across each component is the same as the total voltage.

What does a voltmeter measure?

A voltmeter measures the voltage across a component or section of a circuit.

What is the relationship between voltage and current in Ohm's Law?

According to Ohm's Law, Voltage (V) = Current (I) × Resistance (R).

What does it mean if a circuit has a "short circuit"?

A short circuit occurs when there is a low-resistance path, leading to a surge in current and potential damage.

Why is it important to understand voltage in circuits?

Understanding voltage helps us design safe and efficient electrical systems.

What can happen if too much voltage is applied to a component?

Applying too much voltage can damage the component or cause it to fail.

Convert 1500 millivolts (mV) to volts (V).

1500 mV = 1.5 V (since 1000 mV = 1 V).

Convert 5 volts (V) to millivolts (mV).

5 V = 5000 mV (since 1 V = 1000 mV).

Convert 2000 microvolts (µV) to volts (V).

2000 µV = 0.002 V (since 1,000,000 µV = 1 V).

Convert 0.75 volts (V) to kilovolts (kV).

0.75 V = 0.00075 kV (since 1000 V = 1 kV).

Convert 3.5 kilovolts (kV) to volts (V).

3.5 kV = 3500 V (since 1 kV = 1000 V).

Convert 5000 microvolts (µV) to millivolts (mV).

5000 µV = 5 mV (since 1000 µV = 1 mV).

Convert 10 volts (V) to microvolts (µV).

10 V = 10,000,000 µV (since 1 V = 1,000,000 µV).

Convert 2.5 kilovolts (kV) to millivolts (mV).

2.5 kV = 2,500,000 mV (since 1 kV = 1,000,000 mV).

Convert 0.1 volts (V) to microvolts (µV).

0.1 V = 100,000 µV (since 1 V = 1,000,000 µV).

Convert 300 millivolts (mV) to microvolts (µV).

300 mV = 300,000 µV (since 1 mV = 1000 µV).
