42.6℅ of 230
=(426/10)℅ of 230
=(426×230)/1000
=97980/1000
=97.980
=97.98
Step-by-step explanation:
v=L×W×H
7×10×9=630cm3
Answer:
c
Step-by-step explanation:
The time constant for a series RL circuit is calculated using the following rule:
T = L/R where:
T is the time constant that we need to calculate
L is the value of the inductor = 20 mH = 20 * 10^-3 H
R is the value of the resistance = 2000 ohm
Substitute with the given values in the equation to get the time constant as follows:
T = L/R = (20*10^-3) / (2000) = 10 <span>µsec</span>
