B. 3.2 A
C. 4.6 A
D. 3 A
E. 2 A
F. 13 A
G. 6.4 A
H. 8.8 A
I. 0.5 A
How do I determine the current?
We know that charge, current and time are related by the following formula:
Charge (Q) = Electric current (I) × time (t)
Q = It
Divide by t
I = Q / t
With the above formula, we can obtain the current. Details below:
A. How do I determine the current?
- Charge (Q) = 4.5 C
- Time (t) = 1 s
- Current (I) = ?
I = Q / t
I = 4.5 / 1
I = 4.5 A
B. How do I determine the current?
- Charge (Q) = 192 C
- Time (t) = 1 min = 60 s
- Current (I) = ?
I = Q / t
I = 192 / 60
I = 3.2 A
C. How do I determine the current?
- Charge (Q) = 16.56 KC = 16.56 × 1000 = 16560 C
- Time (t) = 1 h = 1 × 60 × 60 = 3600 s
- Current (I) = ?
I = Q / t
I = 16560 / 3600
I = 4.6 A
D. How do I determine the current?
- Charge (Q) = 1.8 C
- Time (t) = 0.6 s
- Current (I) = ?
I = Q / t
I = 1.8 / 0.6
I = 3 A
E. How do I determine the current?
- Charge (Q) = 3.2 C
- Time (t) = 1.6 s
- Current (I) = ?
I = Q / t
I = 3.2 / 1.6
I = 2 A
F. How do I determine the current?
- Charge (Q) = 33.8 C
- Time (t) = 2.6 s
- Current (I) = ?
I = Q / t
I = 33.8 / 2.6
I = 13 A
G. How do I determine the current?
- Charge (Q) = 147.2 C
- Time (t) = 2.6 s
- Current (I) = ?
I = Q / t
I = 147.2 / 23
I = 6.4 A
H. How do I determine the current?
- Charge (Q) = 7920 C
- Time (t) = 15 mins = 15 × 60 = 900 s
- Current (I) = ?
I = Q / t
I = 7920 / 900
I = 8.8 A
I. How do I determine the current?
Charge (Q) = 7920 C
Time (t) = half hour = 30 mins = 30 × 60 = 1800 s
Current (I) = ?
I = Q / t
I = 900 / 1800
I = 0.5 A
