Question:
A group of Students from UTAS (Physics Unit) visit Al
Hassan Electrical laboratory. Their supervisor gives
them instruction about use of Resistors in different
electrical appliances.
Students are provided with four resistors R,=50
ohm, R2=70 ohm, R3=380 ohm, R4=70 ohm and a
battery of 40 v.
i) If students connect these four resistances in
series, what is the effective resistance?
ii) If students connect these four resistances in
parallel, what is the effective resistance?
iii) If students connect 40 V battery across series
combination, what is the current flowing in the
circuit?
iv) If students connect 40 V battery across parallel
combination, what is the current flowing in the
circuit?
