To Calculate:The value of resistance of a resistor whichis to be connected.
Explanation of Solution
Given:
Value of resistance,
Potential difference across R,
Supplied voltage,
Formula used:
Equivalent resistance for series combination can be obtained by:
Ohm’s law:
Here, I is the current, V is the potential difference and R is the resistance.
Calculations:
The current in a series circuit remains same throughout all the resistors. First, find the current through given resistance and potential drop across that resistor.
The net voltage supply is given. The two resistors would be in series. Let the resistance to be connected be R’ . Then, it can be calculated as follows:
Conclusion:
Thus, a resistor having value
