How many $176 \,\Omega$ resistors (in parallel) are required to carry $5 \,A$ on a $220 \,V$ line?

Several electric bulbs designed to be used on a $220\, V$ electric supply line,are rated $10\, W$. How many lamps can be connected in parallel with each other across the two wires of a $220\, V$ line if the maximum allowable current is $5\, A$?

Compute the heat generated while transferring $96000$ coulomb of charge in one hour through a potential difference of $50\, V$.

Draw a schematic diagram of a circuit consisting of a battery of three cells of $2\, V$ each,a $5\,\Omega$ resistor,an $8\,\Omega$ resistor,and a $12\,\Omega$ resistor,and a plug key,all connected in series. Include an ammeter to measure the current through the resistors and a voltmeter to measure the potential difference across the $12\,\Omega$ resistor. What would be the readings in the ammeter and the voltmeter?

Which of the following terms does not represent electrical power in a circuit?

The values of current $I$ flowing in a given resistor for the corresponding values of potential difference $V$ across the resistor are given below -

$I$ (amperes)	$0.5$	$1.0$	$2.0$	$3.0$	$4.0$
$V$ (volts)	$1.6$	$3.4$	$6.7$	$10.2$	$13.2$

Plot a graph between $V$ and $I$ and calculate the resistance of that resistor.
