Question

Two 80-0 resistors are connected in series with 0.15 A flowing through them?

Find a. Total Resistance (Rt)

b. Voltage drop (Vt) across resistors

c. Current through the circuit

Answer 1

To be given in question

R₁=R₂ $=80\ ohm$

$I=0.15amp$

To be asked in question

(a)total resistance

R_t=?

(b) voltage drop (v)=?

(c) current through the circuit=?

We know that

(a) series combination

$R_{t}=R_{1}+R_{2}$

put value

R_t=160 ohm

(b) voltage drope

$V_{1} =IR_{1}$

$V_{1}=0.15\times80=12Volt$

$V_{2}=IR_{2}$

$V_{2}=0.15\times80=12 Volt$

$V=V_{1}+V_{2}$

$V=12+12=24Volt$

(c) current through the circuit

$I=\frac{V}{R}$

$I=\frac{24}{160} =0.15 amp$
