THANK YOU FOR YOUR HELP.

A heater element rated for 1000 watts and 120 volts is operated from a 100-volt
source. As a result, its:
resistance will decrease.
wattage will increase.
current will increase.
resistance will remain the same.
In a parallel circuit, the current flow through each load resistor:
varies according to the resistance value of the resistor.
is greater for resistors with high resistance values.
is greater for resistors with low resistance values.
is exactly the same value.
Which statement is correct about a parallel circuit?
The total current is equivalent to the sum of the branch currents.
The source voltage is equivalent to the voltage across each load.
The source voltage is equivalent to the sum of the individual voltage drops.
The total resistance is equivalent to the sum of the reciprocal of each load resistance.
