<u>Answer:</u> The correct answer is Option D.
<u>Explanation:</u>
To calculate the value of resistor used in parallel circuit, we need to follow some steps:
- <u>Step 1:</u> Calculation of Voltage from series circuit.
For the calculation of voltage, we will use thew equation given by Ohm's Law, which is:
....(1)
where,
V = voltage = ?V
I = Current flowing = 1.6 A
R = Resistance = (5 + 5) = 10 ohm (In Series, resistance gets added up)
Putting values in above equation, we get:
- <u>Step 2:</u> Finding the total resistance from parallel circuit
As, the voltage passing through the resistors remains the same. Hence, the above voltage can be used:
I = 2A
V = 16V
Putting values in equation 1, we get:
- <u>Step 3:</u> Finding the value of each resistor.
We are given 3 identical resistors that are connected in parallel. In parallel, the total resistance is calculated by using the formula:
Putting values in above equation, we get:
Hence, the correct answer is Option D.
