Answer:

B. 1.7A

Explanation:

R = Resistance

I = Current

V = Voltage (potential difference)

22+4.5 = 26.5

45/26.6= 1.698

Round 1.698 to the nearest hundredth: 1.7

The current of the circuit is 1.7

Answer:

According to Ohm's law ,

V = IR

where ,

V = Potential difference

I = Current flowing

R = Total resistance

here ,

R _{t} = 22Ω + 4.5Ω = 26.5Ω

( since , the resistors are connected in series )

Using Ohm's Law ,

45 = I(26.5) \\  I =  \frac{45}{26.5}  \\  \\ I = 2.5A \: (approx.)

Therefore , option ( 1 ) is correct.

hope helpful~

Why echos are undesirable in a big hall​
KatRina [158]

Answer:

Helloooo

Sound created in a big hall will persist by repeated reflection from the walls until it is reduced to a value where it is no longer audible. The repeated reflection that results in this persistence of sound is called reverberation. In an auditorium or big hall excessive reverberation is highly undesirable

Determine the inductance l of a 0.55-m-long air-filled solenoid 2.7 cm in diameter containing 9000 loops.
faltersainse [42]

Self inductance of a solenoid does not depend on magnetic field or current. When deriving the equation you can see that its self inductance is only dependent on geometric factors
