A
- B.
B
- C.
C
- D.
D
Correct Answer
C. CExplanation
need to increase length AND make it thinner (if make shorter but thinner these have opposite effects as shorter reduces resistance)Rate this question:
-

Q7
- A.
A
- B.
B
- C.
C
- D.
D
Correct Answer
A. AExplanation
Meter x must be current as in series, Y voltage as around the resistor.
Normally voltages are larger than currents so thats why C is not right (also can use V=IR to check)Rate this question:
