CUET and UG exam KEAM Engineering Mock Test Series 2025 Physics Current, Resistance and Electricity Resistance and Resistivity
The supply voltage to a room is 120 \(V\). The resistance of the lead wires is 6 \(\Omega\). A \(60W, 120V\) bulb is already switched on. What is the decrease of voltage (in Volts) across the bulb, when a \(240W, 120V\) heater is switched on in parallel to the bulb?
