What is a semi-Conductor?

• A material with electrical conductivity between that of a conductor and an insulator
• A type of metal with low melting point
• A material with no electrical conductivity
• A material with high electrical resistance

What is the Formula for Ohms Law?

• E = I + R

• E = I / R

• E = I - R

• E = I x R

What is the formula to calculate Total Resistance in series?

• Total Resistance = R1 x R2 x R3 x ...

• Total Resistance = R1 + R2 + R3 + ...
• Total Resistance = R1 - R2 - R3 - ...
• Total Resistance = R1 / R2 / R3 / ...

If RT = 380 Ohms, R1 = 134 Ohms, R3 = 34 Ohms, and R4 = 120 Ohms. What is R2?

• R2 = 200 Ohms
• R2 = 92 Ohms
• R2 = 50 Ohms
• R2 = 300 Ohms

What is the tolerance of a gold band and a silver band of a resistor?

• +/- 7% for gold band and +/- 12% for silver band
• +/- 2% for gold band and +/- 15% for silver band
• +/- 3% for gold band and +/- 8% for silver band
• +/- 5% for gold band and +/- 10% for silver band

What is the memorization tool for the bands of a resistor?
