Ohm's Law

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. It can be expressed as V = I × R.

Front

What is the formula to calculate Voltage?

Back

The formula to calculate Voltage (V) is V = I × R, where I is the current in Amperes and R is the resistance in Ohms.

What happens to the current in a series circuit if one bulb goes out?

Back

If one bulb goes out in a series circuit, the remaining bulbs also go out because the circuit is broken.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where the components are connected across common points or junctions, providing multiple paths for the current to flow.

Front

What is the current through a 6 Ohm resistor with a 12.6 Volt battery?

Back

The current (I) can be calculated using Ohm's Law: I = V / R = 12.6 V / 6 Ω = 2.1 Amps.

Front

What remains constant in a series circuit?

Back

In a series circuit, the current remains constant throughout the entire circuit.

Front

What is resistance?

Back

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

Front

What is the unit of measurement for current?

Back

The unit of measurement for current is Amperes (A).

Front

What is the effect of increasing resistance in a circuit?

Back

Increasing resistance in a circuit decreases the current flow, assuming the voltage remains constant.

Front

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

Back

The relationship is defined by Ohm's Law: V = I × R, meaning voltage is the product of current and resistance.
