Four equal-value resistors are in series with a 12 V battery and 13.63 mA are measured. The value of each resistor is
22 
220
880
88
Answer: Option
Explanation:
Total Resistance, r = 12 / 13.63
= 0.880 in ohms
Total Resistance, r= 880
Each resistance value = r/4
= 880/4
Each resistance value = 220 ohms.

But current is in mA and vol is in V, I think the answer is 22 Ohms.
R = 12v/13.63mA.
R = 12v/13.63mA.

R = 12v/13.63mA,
= 0.880k ohms,
= 880ohms,
4R = 880ohms,
R = 880/4 = 220.
= 0.880k ohms,
= 880ohms,
4R = 880ohms,
R = 880/4 = 220.

You are absolutely correct @Srinidhi.

How?
V/mA = omh?
As per law V/A = Ohm.
V/mA = omh?
As per law V/A = Ohm.

Answer is 22&Ohm;
R = 12 v/.1363 A = 88.04&Ohm;
4R =88&Ohm;,
R = 88/4 = 22&Ohm;.
R = 12 v/.1363 A = 88.04&Ohm;
4R =88&Ohm;,
R = 88/4 = 22&Ohm;.

Answer is 220 ohms.
R=V/I.
R= 12/13.36*10^-3,
R= 898.2.
R/4=224 (approximately).
R/4 means 4 resistors in series.
R=V/I.
R= 12/13.36*10^-3,
R= 898.2.
R/4=224 (approximately).
R/4 means 4 resistors in series.

V = IR.
V = I*(R1+R2+R3+R4)------- R is same so.
V = I*(4R).
12 = 13m * 4 (R).
R= 220.10 ohms.
V = I*(R1+R2+R3+R4)------- R is same so.
V = I*(4R).
12 = 13m * 4 (R).
R= 220.10 ohms.

Total Resistance, r = 12/13.63,
= 0.880 in ohms.
Total Resistance, r= 880,
Each resistance value = r/4.
= 880/4.
Each resistance value = 220 ohms.
= 0.880 in ohms.
Total Resistance, r= 880,
Each resistance value = r/4.
= 880/4.
Each resistance value = 220 ohms.
