Resistors and resistance

What units do we work with when it comes to resistance?

• amps

• light years

• volts

• ohms

Ohm's Law states that

• c² = a² + b²

• E = mc²

• voltage = current x resistance

• y = mx + b

A resistor has a brown multiplier band. This means we multiply by

• 1

• 5¹

• 1⁵

• 10¹

A resistor has a third digit if and only if:

• its resistance is in the trillions

• it is a 4 band

• it is a 5 or 6 banded resistor

• None of the above

What are the first and second digits of this resistor?

• 0.05 and 0

• 2 and 3

• 1 and 2

• 2 and 4

What is the resistance of this resistor?

• 40 ohms

• 47 ohms

• 4 ohms

• 74 ohms

A resistor has the color code of RED-ORANGE-GREEN-BLACK-SILVER. What is the resistance of the resistor?

• 2350 ohms

• 23500 ohms

• 23.5 ohms

• 235 ohms

A resistor has a resistance of 175 ohms. If it has a silver band, then what is the tolerance range of this component?

• 175 ohms - 176 ohms

• 157.5 ohms - 192.5 ohms

• 164.3 ohms - 176.2 ohms

• 173.9 ohms - 181.4 ohms

When a resistor has a resistance of 9.5K ohms, this means the resistance is really:

• 9.5 ohms

• .95 ohms

• 950 ohms

• 9,500 ohms

What is the tolerance range?

• 62.9K - 65.3K

• 61.6K - 71.4K

• 65.0K - 68.1K

• None of the above
