1) Which of the famous scientists in the rules found that electricity could be produced chemically?
2) List 4 properties of an ideal op-amp.
3)
Find V1 and V2.
1) Alessandro Volta
2) It has zero offset voltage, zero output impedance, infinite bandwidth, and infinity input impedance.

===Number 3 Below===

$\frac{20 - V_1}{5} - \frac{V_1 - V_2}{10} - \frac{V_1}{10} = 0$

$\frac{V_1 - V_2}{10} + 4 - \frac{V_2}{20} = 0$

V1 = 20 V
V2 = 40 V

### Re: Circuit Lab B/C

1. Explain briefly what a solenoid is and what it does when connected to a battery (For instance, for a resistor "opposes current," could be an answer).
2. Who invented this device?
3. Find voltage RT in the following circuit.

3. Find voltage RT in the following circuit.
1. A solenoid is a coil of wire designed to create a magnetic field when current is run through it. A solenoid opposes changes in current.
3. 9.62 ohms

1. Correct
2. I believe Ampere invented the solenoid.
3. Correct

Define impedance and explain what it is used for.

Define impedance and explain what it is used for.
Impedance is the complete opposition of the flow of current, unlike resistance, which only slows the speed of the flow of current. It is commonly described as the "resistance to AC current." It is used in capacitors and inductors in the form of reactance, which are used in a variety of appliances, as well as numerous other applications.
