Solution:
Question 1: Find the equivalent resistance RT of given circuit. Write each step of the calculation to get maximum marks. Draw the circuit diagram of each step otherwise you will lose your marks.
Answer: RT = 13.869 omega
Question 3: Answer the following questions.
I). If you wish to increase the amount of current in a resistor from 100mA to 150mA by changing the 20V source, by how many volts should you change source? To what new value should you set it?
Answer: V= 30volts
II). How much power is produced by 500mA of current through a 4.7kO resistor?
Answer: P= 1.175kW
III). There are four equal value resistors in parallel with a 12V source, and 4mA of current from the source. What is the value of each resistor?
Ans: The value of each resistor is = 3k omega
