The source voltage 75v in the circuit.
VT = 75v
15krI = ?
IT = ?
The circuit is both series and parallel but total voltage is given.
R15kI = VT/R15k.
R15kI = 75/15000,
= 5mA.
VT = 75v
15krI = ?
IT = ?

R15kI = VT/R15k.
R15kI = 75/15000,
= 5mA.

RT = 12+15+22 = 49.
RT of parallel = (10x10) /10+10) = 5
So, 49+5 =5 4
I = V/R. = 75/54 = 1.388888889 round off so the total current is 1.4 mA.
RT of parallel = (10x10) /10+10) = 5
So, 49+5 =5 4
I = V/R. = 75/54 = 1.388888889 round off so the total current is 1.4 mA.

R = 12+15+22 = 49kohm.
R = 10/2 = 5kohm.
TR = 49+5 = 54kohm = 54000 ohm.
V = 75V.
I = V/R.
I = 75/54000 = 1.38mA.
R = 10/2 = 5kohm.
TR = 49+5 = 54kohm = 54000 ohm.
V = 75V.
I = V/R.
I = 75/54000 = 1.38mA.

@Thejasvi.
How can you say 5ma is correct?
The current through circuit is 1.4ma and through 15k resistor is also the same because it is connected in series, for your kind information voltage across 15k resistor is not 75 volts. it varies in series circuit.

5mA is correct.
Can anyone clarify it?

One doubt in question they asked to find the current through 15 K resistor. As we know that current in series circuit are same. So by ohm's law we can find that I = V/R.
So I = 75/15K is 5 ma right? Answer any one?
So I = 75/15K is 5 ma right? Answer any one?
