Concise Physics mentions that:
On connecting one more appliance in the same circuit , the resistance of the circuit will increase . Hence , it will reduce the current in the circuit , so each appliance will get less power .
www.allaboutcircuits.com mentions that;
The amount of current in a series circuit is the same through any component in the circuit. This is because there is only one path for current flow in a series circuit.
If the current in the series circuit should remain the same then how does current decreases in a series circuit of the resistance is increased? Why the voltage does not decrease in this case?
