Electricity

Front

What material is commonly used in light bulbs to produce heat and light?

Back

Tungsten

Front

What is the formula to calculate resistance in a circuit?

Back

Resistance (R) = Voltage (V) / Current (I)

Front

If a 500V battery causes a 50A current flow, what is the resistance?

Back

10Ω

Front

What is the direction of electron flow in a circuit?

Back

Electrons flow from the negative terminal to the positive terminal.

Front

What happens to current when resistance in a circuit increases?

Back

A higher resistance causes a smaller current.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

Front

What is the unit of electrical resistance?

Back

Ohm (Ω)

Front

What is the relationship between voltage, current, and resistance?

Back

Voltage = Current x Resistance (V = I x R)

Front

What type of circuit allows current to flow in multiple paths?

Back

Parallel circuit.

Front

What type of circuit has only one path for current to flow?

Back

Series circuit.
