Haya, tuendelee na swali la (c). c) i) Jumla ya vizuizi (total resistance) kwenye mzunguko: Step 1: Tafuta kizuizi sawa cha vizuizi vilivyounganishwa sambamba (2 Ω na 3 Ω). R_p = (R_1 × R_2)/(R_1 + R_2) R_p = (2 \, × 3 \, )/(2 \, + 3 \, ) R_p = (6 \, ^2)/(5 \, ) R_p = 1.2 \, Step 2: Tafuta jumla ya vizuizi kwenye mzunguko. Kizuizi cha 3 Ω kimeunganishwa mfululizo na kizuizi sawa cha sambamba (R_p). R_total = R_series + R_p R_total = 3 \, + 1.2 \, R_total = 4.2 \, Jumla ya vizuizi kwenye mzunguko ni 4.2 . ii) Mkondo wa umeme (current) kwenye mzunguko: Step 1: Tumia Sheria ya Ohm, V = IR, ambapo V ni e.m.f. ya seli na R ni jumla ya vizuizi. I = (V)/(R_total) I = 1.8 \, V4.2 \, I = (18)/(42) \, A I = (3)/(7) \, A I ≈ 0.43 \, A Mkondo wa umeme kwenye mzunguko ni 0.43 A. iii) Usomaji wa voltmeter: Step 1: Voltmeter imeunganishwa kwenye kizuizi cha 3 Ω ambacho kipo mfululizo na betri. Mkondo wa umeme unaopita kwenye kizuizi hiki ni mkondo jumla (I) uliopatikana hapo juu. V_voltmeter = I × R_3 V_voltmeter = (3)/(7) \, A × 3 \, V_voltmeter = (9)/(7) \, V V_voltmeter ≈ 1.29 \, V Usomaji wa voltmeter ni 1.29 V. That's 2 down. 3 left today — send the next one.
