Charge Maths Worksheet
Charge (C) = current (A) x time (s)
Calculating charge using the equation:
a) Current = 10A time = 30s
b) Current = 40A time = 45s
c) Current = 64A time = 180s
d) Current = 37A time = 300s
e) Current = 842A time = 49s
f) Current = 937562 time = 60
g) Current = 3860 time = 210s
h) Current = 492A time = 360s
i) Current = 25A time = 180s
Calculating charge using units:
a) Current = 30A time = 100s b) Current = 450A time = 40s c) Current = 1830A time = 6s
d) Current = 39A time =3600s e) Current = 8A time = 50s
f) Current = 93.7A time =600s
g) Current = 210A time = 3860s h) Current = 4.92A time = 360s i) Current = 1.5A time = 250s
Calculating charge using different units (Remember 1 minute = 60 seconds, 1 hour = 3600 seconds)
a) Current = 45A time = 2 mins b) current = 663A time = 6min c) current = 2A time = 4min
d) current = 1.6A time = 28mins e) current = 3.2A time = 92min f) current = 31A time = 56min
g) current = 25A time = 2hrs
h) current = 62A time = 1.5hrs i) current = 73A time = 1 3/4hrs
