The current in an electrical conductor decreases as its resistance increases (for a constant p.d.); The p.d. across an electrical conductor increases as itsRESISTANCE · -Property of material that tends to oppose current. · FACTORS AFFECTING RESISTANCE · CIRCULAR MILS (CM) · SQUARE MILS (SM) · CONVERSION FROM CM TO SM Thick wires have less resistance than thin wires. Longer wires have more resistance than short wires. The appliances shown below transfer electrical energy to other types of energy. (i) Calculate the total resistance of the two resistors in the circuit. electrical circuit, the current Problem. ▫ Solve for the resistance, R, when V and I are known Combining Ohm's Law and the Power Formula. In a series circuit, the element with the greatest resistance consumes the most power. Follow the rules for parallel circuits. Resistances in parallel combine A battery of e.m.f. 12 V and negligible internal resistance is connected to a resistor network as shown in the circuit diagram.
