Question

A radio receiver has an effective resistance of 300 Ω to the input signal on the antenna downlead. The signal voltage is 700 µV. What is the signal current flow in the antenna downlead?

Answer 1

Answer:I = 2.33 µA

Step-by-step explanation:

Answer 2

I = 2.33 µA

Step-by-step explanation:

given,

Effective resistance (R)= 300 Ω

Voltage of signal (V)= 700 µV

current flow in the antenna = ?

Using ohm's law

V = I R

where I is the current flow

`I = (V)/(R)`

`I = (700* 10^(-6))/(300)`

I = 2.33 x 10⁻⁶ A

I = 2.33 µA

Hence, the current flow in the antenna downloaded is equal to I = 2.33 µA
