The current flowing through R2 can be obtained using the voltage divider rule.
True
The current divider rule is used to calculate the voltage and current of resistors in a circuit.
False
The practical and theoretical results of the circuit experiments will always match exactly.
False
The voltage division rule is used to calculate V out for a given circuit, ignoring the internal resistance of the source E.
True
Using only the current divider formula, I1, I2, I3, and I5 can be determined when I4 = 4A in the given circuit.
False
The Voltage Divider Rule states that the voltage across an element in a series circuit is equal to the resistance of the element divided by the total resistance of the series circuit and multiplied by the total impressed current.
False
The Voltage Divider Rule expression is only valid if different currents flow through all the resistors in the series circuit.
False
The Current Divider Rule states that the current through one of two parallel branches is equal to the resistance of the other branch divided by the sum of the resistances of the two parallel branches and multiplied by the total voltage entering the two parallel branches.
False
The Current Divider Rule is applicable only when there are different voltages across the two parallel branches.
False
The Voltage Divider Rule and Current Divider Rule can be used to analyze both DC and AC circuits.
