John performs an experiment on an electric circuit. he increases the voltage from 25 volts to 50 volts while keeping the resistance constant. what will be the effect of john’s changes on the current? a. the current will increase. b. the current will decrease. c. the current will stay constant. d. the current will stop flowing.

Ohms law states: voltage = current x resistance

while keeping the resistance constant

increases the voltage from 25 volts to 50 volts will increase the current. ans is A

imma come back to you hold on

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
