Study the following circuit and answer the following questions
$(i)$ State the type of combination of the two resistors in the circuit.
$(ii)$ How much current would flow through
$(a)$ $10\, \Omega$ resistor and
$(b)$ $15\, \Omega$ resistors ?
$(iii)$ What would be the ammeter reading ?
$(i)$ Parallel combination.
$(i i)$ $(a) I _{1}=\frac{ V }{ R }=\frac{3}{10}=0.3 A$
$(b)$ $I_{2}=\frac{V}{R_{2}}=\frac{3}{15}=0.2 A$
Current flowing in the circuit
$=0.3 A +0.2 A =0.5 A$
$(iii)$ Ammeter reading is $0.5 A$
How much work is to be done in moving a charge of $2 \,C$ through electric potential difference of $6\, V$ ?
What are the factors on which heat dissipated by a conductor depends ?
What is the commercial unit of electric energy ?
What is the resistance of an ideal ammeter ?
Potential and potential difference are vector quantities.
