Question

if there is no resistance and if there is resistance then?​

Answer 1

Answer:

If there is no resistance then it means that their is no current limiting factors. If the supply input is more than the desired input for the appliance then it has the tendency to cause short-circuit in the appliance. If w go for the theoritical part, then we can say that according to Ohms law V=IR.

Answer 2

Answer:

If there really were no resistance in the circuit, the electrons would go around the circuit, and arrive back at the beginning of the circuit with as much energy as the potential difference (the voltage). ... Current will flow, and since the resistance is low -- though not zero -- you will just get a really large current.

The relationship between resistance and wire length is proportional . ... When resistance is increased in a circuit , for example by adding more electrical components , the current decreases as a result.
