Question

A resistor is connected to an ac source having a fre-quency of 100 Hz, and maximum

potential differ-ence of 170 V. To produce a maximum current through the circuit of
1.7 A, what must the value of the resistance be?

Answer 1

To produce a maximum current of 1.7 A through the circuit, the value of the resistance should be 100 ohms.

Step-by-step explanation:

To find the value of resistance, we can use Ohm's Law which states that the current flowing through a resistor is equal to the voltage across the resistor divided by the resistance. In this case, the maximum potential difference is 170 V and the maximum current is 1.7 A. So, the resistance can be calculated as:

Resistance = Voltage / Current

Substituting the given values:

Resistance = 170 V / 1.7 A = 100 ohms

Therefore, the value of the resistance should be 100 ohms to produce a maximum current of 1.7 A.
