Given that,
Three resistors of resistances 2 Ω, 3 Ω and 4 Ω are connected in series with a 15 V supply.
Solution,
The equivalent resistance in series combination is given by :
(i) Total resistance of the circuit is equal to 9 ohms.
(ii) Let I be the total current. Using Ohm's law as follows :
(iii) Voltage drop across 2 ohm resistor is :
Voltage drop across 3 ohm resistor is :
Voltage drop across 4 ohm resistor is :
Hence, this is the required solution.
