Two identical bulbs in parallel in a radio create a total resistance of 15 ohms in the circuit. What's the resistance of each of the bulbs A. 10 ohms B. 7.5 ohms C. 45 ohms D. 30 ohms

Answer

letter B is the answer because 7.5+7.5=15

The resistance of each of the bulbs will be 30 ohms. The correct option is D.

To resist the passage of current, use a resistor. When a resistor is included in a circuit, the amount of current that flows through it drops.

Using ohms as the unit, resistance acts as a gauge to quantify how easily current will flow through a circuit.

When resistance falls, current rises, and when resistance rises, current falls. In order to make sure that current flows in circuits at the proper rate, resistors are crucial.

Here, it is given that:

Total resistance is 15 ohms.

We know that, two identical resistors in parallel have an equivalent resistance half the value of either resistor.

So, the total resistance of 15 ohms have the resistance of each of the bulbs as 30 ohms.

Thus, the correct option is D.
