A current of 4mA is flowing through a conductor in 20s calculate the charge flowing through itI need it quickly plsstep by step answer |
Answer» Given:-→ Current flowing = 4 mA → Time = 20 s To FIND:-→ Charge flowing through the conductor. Solution:-Firstly let's convert the unit of current from mA to A. ⇒ 1 mA = 0.001 A ⇒ 4 mA = 4(0.001) ⇒ 0.004 A ________________________________ Now, we know that :- i = Q/t Where :- • i is the current flowing. • Q is the charge. • t is time. Substituting VALUES, we get :- ⇒ 0.004 = Q/20 ⇒ Q = 20(0.004) ⇒ Q = 0.08 C Thus, the charge flowing is 0.08 C . |
