Total questions: 15
Worksheet time: 14mins
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

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:
