Ahh okay thank you !, So Xc = 796.178 Now i know the reactance how i can get the current ? i haven't been able to find a formulae for it. Thank you in advance !

Homework Statement c) Calculate the current flowing when a 4 uF capacitor is connected across 240V 50 Hz supply ? Homework Equations XC = 1/(2πfC) The Attempt at a Solution XC = 1/(2πfC) XC = 1/(2π 50*0.000004) XC = 1/(2π* 0.0002) XC = 1/(6.28* 0.0002) XC = 1/ 0.001256...

Also to calculate the maximum voltage, would it be correct to say ... V=IR V = 9.76*9500 ( 9500 because that is the lowest resistance point ) V = 0.00976*9500 V = 92.72 volts Thank you

oh okay, 1.so sqrt 0.00001 = 3.16 2. Would it be 3.16 amps then ? 3. Okay so is it correct to say that to calculate maximum current, i need to calculate the maximum resistance, using the tolerance of in this case 5 percent,. Then repeat the previous formulae I = sqrt(P/R) with the new...

Homework Statement B) What is the maximum permissible current which can flow through a 1 watt resistor colour coded Brown, Black Orange, Gold ? C ) what is the highest voltage that can be applied to the resistor in part ( B ) ? Homework Equations P = I^2 * R The Attempt at...

Thank you :), Oh right so it's another way of saying ohms. Lovely, It would be 20 volts i believe since the terminal voltage is 20 volts so that should be the voltage passing through the resistor. Would the E.M.F. be referring to the voltage after the internal resistance has been...

Okay thank you, well they haven't actually provided the value of V and E. The known values are : 24 Volt Supply with a terminal voltage of 20 volts when connected to a 40R load resistor. That is all the information that was provided, Also it says 40R, what does R refer to ? Thank you...

Homework Statement A 24 voltt supply has a terminal voltage of 20 volts when connected to a 40R Load Resistor. Calculate the internal resistance of the supply State the conditions under which maximum power will be transferred to load. Homework Equations V = E - Ir V = p.d...
