How will INCREASING the resistance of the variable resistor in FIGURE 1 affect each of the following quantities?

A charge flow of 15 coulombs passed through the filament lamp in a time of 60 seconds. Calculate the current in the lamp.

When the current in the filament lamp is 0.12 A, the potential difference across the lamp is 6.0 V. Calculate the resistance of the filament lamp.

What type of error does the ammeter display?

• A positive error

• A random error

• A zero error
