if the current through resistor is 5 mA. how many coulmobs of charge flow through this resistor in one minute?
Charge= current*time=.005 columbs/sec * 60 sec...
so my answer would be 0.3 coulombs
To determine the amount of charge flowing through a resistor in one minute, you need to know the current passing through it.
In this case, the current through the resistor is given as 5 mA (milliamperes). However, we need the current in amperes (A) to ensure consistent units for calculations.
To convert mA to A, divide the given value by 1000:
5 mA ÷ 1000 = 0.005 A
So, the current passing through the resistor is 0.005 A.
Now, to calculate the coulombs of charge flowing through the resistor in one minute, we can use the formula:
Charge = Current × Time
The time is given as one minute, which we need to convert to seconds, as the SI unit for time is seconds.
1 minute = 60 seconds
Now, let's calculate the charge flow:
Charge = 0.005 A × 60 s
Charge = 0.3 coulombs
Therefore, 0.3 coulombs of charge flow through the resistor in one minute, given a current of 5 mA.
