How does current change.

if the voltage is increased, the current will increase provided the resistance of the circuit does not change.

Explanation:

by using high vb

or decreasing the resistance by connecting them parallel

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
