Question

2 resistance of 3 ohm and a wire resistance were connected in series across 12V battery if voltage drop across a resistance is 6V find :a) potential across 3ohm resistors b) current through the resistance c) equivalent resistance of battery​

Answer 1

Answer:

If no internal resistance is present in voltage supply, the potential difference across the resistor is equal to supply voltage. Now imagine the same circuit but total current is given as 0.1A . The potential difference is V=IR=0.1*5=0.5V, which basically means the statement above is incorrect.
