A$\frac{{14}}{3}\,\,\Omega $
a (a) The given circuit is a balanced Wheatstone bridge, hence it can be redrawn as follows
$ \Rightarrow \,\,\,\,\,\,{R_{eq}} = \frac{{7 \times 14}}{{(7 + 14)}} = \frac{{14}}{3}\Omega $.

In an electric heater $4\, amp$ current passes for $1$ minute at potential difference of $250\, volt$, the power of heater and energy consumed will be respectively
An insulating pipe of cross-section area $'A'$ contains an electrolyte which has two types of ions $\rightarrow$ their charges being $-e$ and $+2e$. $A$ potential difference applied between the ends of the pipe result in the drifting of the two types of ions, having drift speed $= v$ ($-ve$ ion) and $v/4$ ($+ve$ ion). Both ions have the same number per unit volume $= n$. The current flowing through the pipe is
An electric heater consists of a nichrome coil and runs under $220 \,V$, consuming $1 \,kW$ power. Part of its coil burned out and it was reconnected after cutting off the burnt portion.The power it will cunsume now is
