Front

What is charging by induction?

Back

Charging by induction is the process where a charged object is brought near a neutral object, causing a separation of charges within the neutral object.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). The formula is I=V/R.

Front

What is the formula for Electric Power?

Back

The formula for Electric Power is P=IV, where P is power, I is current, and V is voltage.

Front

Why do we ground buildings?

Back

We ground buildings to prevent electrical hazards by providing a safe path for excess electricity to flow into the ground.

Front

What is a Conductor?

Back

A conductor is a material that allows the flow of electric charge.

Front

What is a Resistor?

Back

A resistor is a material that resists the flow of electric charge, used to control current in a circuit.

Front

What is Voltage?

Back

Voltage is the electric potential difference between two points in a circuit, measured in volts (V).

Front

What is Current?

Back

Current is the flow of electric charge in a circuit, measured in amperes (A).

Front

What is Resistance?

Back

Resistance is the opposition to the flow of electric current, measured in ohms (Ω).

Front

What is the relationship between Voltage, Current, and Resistance?

Back

The relationship is defined by Ohm's Law: V = IR, where V is voltage, I is current, and R is resistance.
