Power = (voltage)2/Resistance
Resistance = (voltage)2/(Power)
The standard household voltage in North America is 117 V.
Resistance = (117)2/(60) = 228 ohms (rounded)

When using a 60.0 W light bulb in a household circuit what is the resistance?
To calculate the resistance of the 60.0 W light bulb, you need to know the voltage of the household circuit. Using the formula P = V^2 / R (where P is power in watts, V is voltage in volts, and R is resistance in ohms), you can rearrange to solve for resistance: R = V^2 / P. Substitute the given power (60.0 W) and the voltage of your household circuit to find the resistance.
When more light bulbs are added in parallel to a circuit what happens to the total resistance of the circuit?
When more light bulbs are added in parallel to a circuit, the total resistance of the circuit decreases. This is because in a parallel circuit, the reciprocal of the total resistance is equal to the sum of the reciprocals of the individual resistances. More paths for current to flow mean less overall resistance in the circuit.
Which circuit was the light bulb the dimmest?
The light bulb was likely the dimmest in the circuit where it had the highest resistance, creating more opposition to the flow of current, resulting in less brightness.
In a series circuit when adding light bulbs does the current change?
In a series circuit, adding more light bulbs increases the resistance in the circuit. As a result, the total current in the circuit decreases because the voltage remains constant. The current is shared among the components in a series circuit, so adding more bulbs decreases the current that flows through each bulb.
What would happen to the current in a simple circuit if a bulb with a higher resistance were used?
If a bulb with higher resistance is used in a simple circuit, the total resistance in the circuit would increase. According to Ohm's Law (V=IR), with an increase in resistance, the current in the circuit would decrease since the voltage supplied remains constant.
