Telangana Board Solutions for Chapter: Electric Current, Exercise 1: Exercise 1

A house has $3$ tube lights, two fans and a Television. Each tube light draws $40 \mathrm{W}$. The fan draws $80 \mathrm{W}$ and the Television draws $60 \mathrm{W}$. On the average, all the tube lights are kept on for five hours, two fans for $12$ hours and the television for five hours every day. Find the cost of electric energy used in $30$ days at the rate of Rs. $3.00$ per $\mathrm{kWh}$.

A uniform wire of resistance $50 \mathrm{\Omega }$ is cut into five equal parts. These parts are now connected in parallel. Then the equivalent resistance of the combination is

A charge is moved from a point A to a point B. The work done to move unit charge during this process is called 

Joule/coulomb is the same as

The resistors of values $2 \mathrm{\Omega }, 4 \mathrm{\Omega }, 6 \mathrm{\Omega }$ are connected in series. The equivalent resistance in the circuit is

The resistors of value $3 \mathrm{\Omega } , 6 \mathrm{\Omega },18 \mathrm{\Omega }$ are connected in parallel. The equivalent resistance in the circuit is

The resistors of values $6 \mathrm{\Omega }, 6 \mathrm{\Omega }$ are connected in series and $12 \mathrm{\Omega }$ are connected in parallel. The equivalent resistance of the circuit is

The current in the wire depends
