A total charge of 7.0 mC passes through a cross-sectional area of a nichrome wire in 4.4 s. What is the current in the wire? The fundamental charge is 1.602 × 10−19 C. Answer in units of A.

I = 0.00159 A

Explanation:

Given:

Charge q= 7 mC = 7 × 10⁻³ C, Time t = 4.4 s

To Find: Current I = ?

Solution:

the formula is I = q/t

I = 7 × 10⁻³ C / 4.4 s

I = 0.00159 A

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

the device is called “ rocket engine”
