What is internal resistance of source bettery
Electric Circuits
A battery having an e.m.f. of 110 V and an internal resistance of 0.2 Ω is connected in parallel with another battery having an e.m.f. of 100 V and internal resistance 0.25 Ω. The two batteries in parallelare placed in series with a regulating resistance of 5 Ω and connected across 200 V mains, as shown. Calculate :(i) The magnitude and direction of the current in each battery.(ii) The total current taken from the supply mains

2.7 3.3 2.9 4.7 5.6
6.8 8.2
You are to design a non-inverting amplifier circuit. One of the external resistors (R1) has value of 100Ω. Determine the resistance of the 2nd external resistor (R2), which would produce a gain of 44. Then draw the resistor circuit using the standard resistors to get as close as you can to the desired value.
