Choose all of the true statements regarding the relationship between voltage, resistance, and current. current is measured in amps and is represented by the symbol "δ" the relationship between current, voltage, and resistance is mathematically defined by ohm's law. current is the flow of electrons through a circuit. ohm's law is mathematically represented by the equation v=i/r when solving for resistance in a current and both voltage and current are known values, the equation to solve reads i =v*r if the voltage in a circuit is increased, the current will also increase.

You are asked to explain the relationship between current and voltage. select the statement that would be an accurate reply. a. voltage is the force that resists the flow of electricity; if we increase the voltage, and do not change the resistance, we will decrease the current. b. voltage is the force that drives electric current. when we increase the voltage, and do not change the resistance, we have an increase in current. c. voltage is how much current passes a point in a given time. if we want to increase the voltage, we would need to increase the current. d. voltage describe the amount that a material resists the flow of electrons. if we want to increase the voltage we need to increase the resistance.
