Question

Calculate the value of resistor X.
8ν

|= 0.5A
4 Ω
4 Ω
12Ω
6 Ω​

Answer 1

Answer: Given: V=12V, Resistance of A=4Ω, Resistance of B=6Ω, Internal battery resistance =2Ω

(i) Total Resistance =4+6+2=12Ω

I (current in circuit)=

Totalresistance

=1amp

(ii) Voltage drop Ir=1×2=2volt

Terminal Voltage = emf - Voltage drop

                            =12−2=10 volts

(iii) Potential difference across 6Ω=IR

                                                         =1×6=6V

(iv) Energy spent =I
