Answer:
Current = 0.889 A
Explanation:
Given:
rms Voltage , [tex]V_{rms}[/tex] = 220 V
resistance, R = 350 Ω
We know current across resistance
[tex]I_{R}=\frac{V}{R}[/tex]
where [tex]I_{R}[/tex] is current across voltage
R is resistance
V is voltage
From relation between rms volatge,[tex]V_{rms}[/tex] and source voltage, V
[tex]V = \sqrt{2}.V_{rms}[/tex]
[tex]V = \sqrt{2}\times 220[/tex]
[tex]V = 311.2[/tex] volt
Therefore substituting 311.12 volt and 350 Ω for voltage and resistance respectively in the current across resistance equation, we get
[tex]I_{R}=\frac{V}{R}[/tex]
[tex]I_{R}=\frac{311.12}{350}[/tex]
[tex]I_{R}= 0.889[/tex] A
Therefore, amplitude of current across resistance is 0.889 A
