Current Electricity)
Q1. The storage battery of a car has an emf of 12 V. If the internal resistance of the batteryis 0.4Ω, what is the maximum current that can be drawn from the battery?
Q2. Three resistors 1 Ω, 2 Ω, and 3 Ω are combined in series. What is the totalresistance of the combination?
Q3. Three resistors 2 Ω, 4 Ω and 5 Ω are combined in parallel. What is the totalresistance of the combination?
Q4. Three resistors 2 Ω, 4 Ω and 5 Ω are combined in parallel. If the combination is connected to a battery of emf 20 V and negligible internalresistance, determine the current through each resistor, and the total current drawn fromthe battery.
