How will you infer with the help of an experiment that the same current flows through every part of the circuit containing three resistances in series connected to a battery?
Identify the circuit (Figure) in which the electrical components have been properly connected.
Define power. State the difference between $1$ watt and $1$ watt hour. Establish the relationship between unit of electric energy and $SI$ unit of energy. An electric heater rated $1000\, W / 220 \,V$ operates $2$ hours daily. Calculate the cost of energy to operate for $30$ days at the rate of ₹ $5.00$ per $k W h$
In an electrical circuit three incandescent bulbs $A, B$ and $C$ of rating $40\, W, 60\, W$ and $100 \,W $ respectively are connected in parallel to an electric source. Which of the following is likely to happen regarding their brightness?
A hot plate of an electric oven connected to a $220\, V$ line has two resistors $A$ and $B$ each of $22\, \Omega$ resistance. These resistors may be used separately, in series or in parallel. Find the current flowing in all the three cases.
