Question

3 resistors of 15ohm 20ohm 30ohm are connected in a series with 20volt calculate their combined resistance the current that flows in the circuit in each resistor and potential difference across each resistor​

Answer 1

if the resistance of 15 20 and 30 ohms are connected in parallel then the total resistance is 65 and they are connected with 20v battery then the total current produced by Dam across the resistor isby putting in the formula that we is directly proportional to I R. .
show the total current is 3.75 ampere

Answer 2

For simplicity I have taken the value of current as 0.3A(approx) instead of the exact 0.307A.
