i) Five similar resistors, each of resistance R, are joined in series to a battery, and a current of 2.86 A flows in the circuit. Now, the other resistor of resistance R is added to the circuit, in series with the rest of the resistors. Determine the new current in the circuit.
ii) Five similar resistors, each of resistance R, are joined in parallel to a battery, and a current of 2.86 A flows in the circuit. Now, the other resistor of resistance R is added to the circuit, in parallel with the rest of the resistors. Determine the new current in the circuit.
iii) Five similar resistors, each of resistance R, are joined in series to a battery, and a current of 2.86 A flows in the circuit. Now, the other resistor of resistance R is added to the circuit, in parallel with the battery. Determine the new net current in the circuit.
