a) The combined resistance of the above circuit. Step 1: Calculate the equivalent resistance of the parallel combination of the 4\, and 6\, resistors. (1)/(R_p) = (1)/(4\,) + (1)/(6\,) (1)/(R_p) = (3)/(12\,) + (2)/(12\,) (1)/(R_p) = (5)/(12\,) R_p = (12)/(5)\, = 2.4\, Step 2: Calculate the total combined resistance (R_total) by adding the series resistor (2\,) to the parallel equivalent resistance (R_p). R_total = 2\, + R_p R_total = 2\, + 2.4\, R_total = 4.4\, The combined resistance of the circuit is 4.4 . b) The current flowing through the ammeter. Step 1: Use Ohm's Law (V = I · R) to find the total current (I_total) flowing from the voltage source, which is measured by the ammeter. I_total = V_sourceR_total I_total = (12\,V)/(4.4\,) I_total = (120)/(44)\,A = (30)/(11)\,A I_total ≈ 2.73\,A The current flowing through the ammeter is 2.73 A.
