2.
The unit of electrical charge is the
3.
Current flows in a circuit when
4.
The minimum resistance value for a blue, gray, red, silver resistor is
Answer: Option
Explanation:
Because of 10% tolerance(last color silver), this resistance may vary 10% of 6800.
Minimum resistance value = 6800 - 680 = 6120
Maximum resistance value = 6800 + 680 = 7480
5.
The maximum resistance value for a brown, red, yellow, gold resistor is
