(a) For parallel resistors: ( \frac1R_t = \frac13 + \frac16 = \frac26 + \frac16 = \frac36 = \frac12 ). Therefore, ( R_t = ) 2 Ω (b) Voltage is the same across all branches in a parallel circuit (4 V). Using Ohm's Law, ( I = \fracVR = \frac43 = ) 1.33 A (or 1(\frac13) A)
Once we understand static charges, we can explore the flow of charges, which is known as electric current. Think of electricity like water flowing through pipes;
Controls the flow of current by opening or closing the circuit . Two dots with a line. Provides electrical energy to the circuit . Long and short parallel lines. Part C: Understanding Circuits 1. True or False?
Electric current is the rate of flow of electric charges (electrons) through a conductor . The SI unit is the ampere (A) .
Teachers routinely dock marks for missing or incorrect units. Always double-check that current is in Amperes (A), voltage in Volts (V), and resistance in Ohms ( Ωcap omega
