## Friday Free Board Quiz – the prize is Soldering Iron – Resonant circuits

CHN-SLD802 is low cost soldering iron with temperature regulator.

You can win this soldering iron! To participate in the Quiz is enough to re-tweet the Twitter Quiz announcement message.

The Quiz question is: In a RLC series resonant circuit the voltage on the Capacitor leads is 10V the voltage on Inductor leads is 10V and the voltage on Resistor leads is 5V. What is the value of the source voltage which drive this RLC circuit?

You have time to re-tweet and/or answer until Monday 21th of March.

In Monday we will post the correct answer and ask random.org to generate random number in range then announce the winner and ship the board by post/airmail.

Good Luck!

1. 15 V AC

2. 5Vac. Resonant ==> i/jCw = ijLw

Vs^2 = Vr^2 + (Vl – Vc)^2
Source voltage is 5V
