ASSIGNMENT

1. A resistance of 6ohms is connected in series with another of 3ohms. If a potential difference of 9V is applied across the combination, what is the p. d. across the 6ohms resistance.

Equivalent resistance in series = 6 + 3 = 9 ohms

Current = V/R (ohm's law)

Current = 9/9 = 1 A

P.D. across 6 ohms = IR (ohm's law)

= 1A × 6Ω = 6V

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper
