Two bulbs rated 100 W, 220 V and 60 W, 220 V are connected in series across 220 V. Which bulb glows brighter?
View solution →A 60 W bulb is connected to a 120 V supply. What is the current (in mA) drawn by the bulb?
View solution →The terminal voltage of a battery is always less than or equal to its EMF when it delivers current.
View solution →A cell of EMF 6 V and internal resistance 1 Ω is connected to an external resistor of 2 Ω. The terminal voltage is:
View solution →In a balanced Wheatstone bridge with arms 4 Ω, 6 Ω, 10 Ω and $S$, the value of $S$ (in Ω) is:
View solution →A Wheatstone bridge is balanced when $P/Q = R/S$. In the balanced state, the current through the galvanometer is:
View solution →Kirchhoff's loop (voltage) rule is based on conservation of:
View solution →Kirchhoff's junction rule is a statement of conservation of:
View solution →The resistance of a uniform wire of length $L$ and area $A$ is $R$. If it is stretched to double its length (volume constant), the new resistance is:
View solution →Two resistors of 3 Ω and 6 Ω are connected in parallel. The equivalent resistance is:
View solution →Three resistors of 2 Ω, 4 Ω, and 6 Ω are connected in series across a 12 V battery. The current in the circuit is:
