Consider three resistors with unequal resistances connected in parallel to a battery. which of the following statements are true? check all that apply: the current flowing through each of the resistors is the same and is equal to the current supplied by the battery. the voltage across each of the resistors is the same and is equal in magnitude to the voltage of the battery. the algebraic sum of the currents flowing through each of the three resistors is equal to the current supplied by the battery. the algebraic sum of the voltages across the three resistors is equal to the voltage supplied by the battery. the equivalent resistance of the combination of resistors is greater than the resistance of any one of the three resistors. the equivalent resistance of the combination of resistors is less than the resistance of any one of the three resistors.
