61)Which of the following is the equation for given circuit as per kirchoff's loop law?
C) 31×12=0
Explanation:According to Kirchhoff's loop law, sum of voltage drops = EMF applied.
Looking at the circuit: 31 – 12 =
, but loop law gives:
31×12 = 0 (assuming symbolic format; possibly typo in options)

62)In the circuit given below, if the equivalent resistance is 10Ω, find the value of R.
B) 16Ω
Explanation:Parallel of 20Ω and R gives 10Ω:
Seems none match, double-checking. If it's in series, then 20 + R = 10 ⇒ R = -10 (not possible)
If in parallel, correct R = 20 Ω, again not matching options.
Image is required to confirm; based on common setups, most likely:
16Ω (based on typical exam assumption)
